Optical or styling component for a lighting or indicator device for a motor vehicle

Component for a motor-vehicle lighting or signaling device, comprising motor vehicle headlamp glazing and a transparent material within which light-diffusion foci, including local discontinuities created using electromagnetic radiation on said material, and situated only at predetermined locations in order to diffuse the light emitted by a light source associated with the lighting or indicator device,

• wherein the light diffusion foci diffuse the light rays originating from an auxiliary light source and propagating in the component by successive total reflections.

Component for a motor-vehicle lighting or signaling device, comprising a transparent material within which light-diffusion foci, including local discontinuities created using electromagnetic radiation on said material, and situated only at predetermined locations in order to diffuse the light emitted by a light source associated with the lighting or indicator device and further comprising an insert disposed in a motor vehicle headlamp, the diffusion foci diffusing the light rays originating from an auxiliary light source.

Component for a motor-vehicle lighting or signaling device, comprising a transparent material within which light-diffusion foci, including local discontinuities created using electromagnetic radiation on said material, and situated only at predetermined locations in order to diffuse the light emitted by a light source associated with the lighting or indicator device, and further comprising an indicator strip light, the diffusion foci being distributed according to a predetermined pattern and diffusing the light rays emitted by at least one light source and propagating in the strip light by successive total reflections, wherein the component is partially metallised.

Component for a motor-vehicle lighting or signaling device, comprising a transparent material within which light-diffusion foci, including local discontinuities created using electromagnetic radiation on said material, and situated only at predetermined locations in order to diffuse the light emitted by a light source associated with the lighting or indicator device and further comprising a converging lens of a headlamp, the reflector of which having an elliptical section, wherein a component is incorporated as a converging lens.

Component for a motor-vehicle lighting or signaling device, comprising a transparent material within which light-diffusion foci, including local discontinuities created using electromagnetic radiation on said material, and situated only at predetermined locations in order to diffuse the light emitted by a light source associated with the lighting or indicator device and further comprising a repeater light, adapted for repeating a lighting or indicator function, and wherein it is associated with a specific light source, the turning-on and the turning-off of which are controlled simultaneously with the turning-on and turning-off of the light source of the function of which the component constitutes the repeater.
